Figure 4-13 Typical example of a PWM signal

The PWM frequency is derived from the digital clock via

(4.3)

The min/max values given in Table 4-18 take into account the internal digital clock variation specified in

Chapter 4.3.7. If external clock is used, the variation of the PWM frequency can be derived from the variation of

the external clock using Equation (4.3).
